+# Regression tests for the narrow VC6 compat/msvc600/stdint.h shim.
+#
+# Skipped (not failed) when Wine + MSVC600 are unavailable, matching the other
+# VC6 probe test scripts. The live check is compile-only: it verifies that the
+# fixture using representative uint8_t/uint32_t/uint64_t load/store/rotate
+# patterns (the exact subset cpython/Modules/_blake2/impl/blake2-impl.h uses)
+# reaches cl.exe exit 0, and that <stdint.h> and <inttypes.h> can both be
+# included in the same translation unit without a duplicate-typedef error.
+#
+# Usage: scripts/vc6-probe-stdint.test.sh
